LensCLEANing JVAS B0218+357 to determine H0
Olaf Wucknitz
文献摘要
We use the radio ring in JVAS B0218+357 to constrain the mass models with LensCLEAN. H0 is determined from the resulting model and the time delay. B0218+357 is one of the best systems to reduce systematic errors in H0 and may thus be called a “golden lens”.
